G2 Haskell Symbolic Execution Engine

About

G2 performs lazy symbolic execution of Haskell programs to detect state reachability. It is capable of generating assertion failure counterexamples and solving for higher-order functions.

Dependencies

GHC: https://www.haskell.org/ghc/
Custom Haskell Standard Library: https://github.com/BillHallahan/base-4.9.1.0
Z3 SMT Solver: https://github.com/Z3Prover/z3

Setup:

Install GHC.
Install Z3. Ensure Z3 is in your system's path.
Pull the Custom Haskell Standard Library into ~/.g2 by running bash base_setup.sh.

Command line:

Reachability:

cabal run G2 ./tests/Samples/Peano.hs add

LiquidHaskell:

cabal run G2LH ./tests/Liquid/Peano.hs add

Arguments:

--n number of reduction steps to run
--max-outputs number of inputs/results to display
--smt Pass "z3" or "cvc4" to select a solver [Default: Z3]
--time Set a timeout in seconds
